There are several factors to consider when choosing a dedicated server for your forum site. First, the server's processor power is crucial for efficiently processing database queries and forum operations. I think that a powerful processor like Intel Xeon will be quite enough for its operation.
In addition, sufficient RAM is needed to maintain the database and process simultaneous user activity. Considering that you currently have 12 GB of RAM, you may want to consider increasing your RAM to at least 16 GB or higher.
I would go for NVMe drives if I were you, as they are much better at storing and processing database queries.
